75% 450 times 100 divided by 600
X=?
Well this is very complicated my child.
-SC
Part A: Connor is wrong, this is because the inequality 9x<27 means that 9x is LESS than 27. For example, if x was 17, it would mean 9 times 17 (153) which is WAAAY more than 27. Connor's statement is nonsense.
Part B: x could equal 2 or less. This is because anything over 2 will not fit with the inequality. (if x was 3 that would make it equal to 27 and that won't be right). 9 times 2 is 18 which is less than 27, so is 1 and so on :)
1)
We calculate the total number of new light fixtures.
Total number of new light fixtures=(24 new fixtures/1 floor)(4 floors)=
=96 new fixtures.
2)
We calculate the total number of work hours
20 minutes=20 minutes * (1 hour/60 minutes)=1/3 hour.
1 electrician-----------1/3 hour----------1 new fixture
2 electricians---------- x ------------96 new fixtures
1 elec.*1/3 hour*96 nex fixtures=2 elect. * x * 1 new fixture.
x=(1 elec. *1/3 hour * 96 nex litght fixtures) / (2 elect.* 1 new fixture)=
=16 hours.
3)
We calculate the total number of days that it take two electricians to complete the installations.
1 day-------------8 work hours
x------------------16 work hours
x=(1 day* 16 work hours) / (8 work hours)=2 days
Answer: 2 days.
